Application filed October 28, 1926. Serial No. 144,835.

This invention relates to improvements in transfer devices for invalids, and has for one of its particular objects to provide means, in connection with an invalid chair, to facilitate the removing of a patient from the bed tov the chair in a manner least disturbing to the patient.

Another object is to accomplish this end by a simple structure which may be e1n bodied in a chair, as an integral part thereof, or fashioned so asto form a separate acces-sory of the same.

With these and incidental objects in view,

the invention consists ofcertain novel features of construction and combination of parts, the essentialelements are hereinafter described with reference to the drawings which accompany and form a part of this specification, and in which Fig. 1 is a side elevational view of an invalid chair having my transfer device forming an integral part thereof, only a fragmentary part of the bed being shown;

Fig. 2 is a perspective view of the device;

Fig. 3 is a fragmentary cross sectional view along the plane of line 3-3 in Fig. 1;

Fig. 4 is an enlarged fra mentary perspectlve view of a preferred orm of an adjustable support for the device; and

Fig. 5 is a side elevational view, similar to Fig. 1, but showing the transfer device as a.

separate accessory to the usual form of invalid chair.

Like characters of reference denote similarparts throughout the several views and the ollowing specification.

10 is a frame structure, having a square top section 11, and downwardly extending legs 12 connected together at their lower ends by horizontal strips 13. 14 are large front wheels and 15 small rear wheels fastened to the bottom of the frame 10, as is common to.invalid chairs. Hinged to the back of the frame 10 at its top are two par allelly disposed members 16, adapted to swing upwardly, as indicated in dotted lines in F1 1. 17 are extensions to members 16, hinge thereto and adapted to swing downwardly, as also indicated in dotted lines in Fig. 1. Members 16, extensions 17 and the top of frame 10 in alignment with members 16 are each provided with a registering groove or track 18. 19 is a cross piece near the outer ends of members 16, between them, and 20 is asimilar connection between extensions 17. The top of frame 10 is caned at 21-and the space between members 16 at 22. Fastened to the underside of members 16, nearwhere extensions l7are hinged thereto, are ad'ustable a brac et 24 having a groove 25 fastened to the member 16 by screws 27, and an extenslon 28 l I having also a groove 29 and a recess 30 atits bottom adapted to restupon the side braces 31 of a pose of varymg the length of the support 23. Mounted upon the top 11 of the frame 10 1s a platform 33 having-four small'rollers 34 at its bottom, of which two on each side caned seat 39 between the frame, and a back rest 40, which latter may be dispensed with, if so found desirable. Auxiliary seat 37 is fastened to platform 33 by means of a centrally disposed pivot 41 which permits of revolving seat 37 about this pivot as an axis. 55

42- are small ball bearin s at the underside of the auxiliary seat, riding on top oflatform 33, to facilitate the revolving o the seat.

In the modification shown in usual form of invalid chair is shown, which has a back 43 and the leg support 35 and foot rest 36 directly fastened to the frame 10. Members 16 are laid over the seat part of frame 10, and are hinged also at 16.

The reference numbers used in the drawing of the-modification are otherwise the same as employed for corresponding parts in the construction previously described, and the parts are essentially" the same. able supports'23 for the members 16, however, are omitted.

The operation of the device is as follows:

The structure is wheeled into the position shown in Fig. 1 alongside of the bed in 105 which the patient is lying. Track members,

16 are then let down to a izontal position, and extensions 17 are swung around to a similar osition, resting upon the top of the bed. M

sides of the bed by supports '23 which are adjusted to bring them in as near a horisupports23 comprising each 00 bed. 32 is a set screw 65 ,through the grooves'25 and 29 for the pur- 35 is a leg support-hinged 7 Fig. 5, a no The adjustembers 16 are supported upon the no zontal position as possible. The auxiliary seat .37 and platform 33 with its leg support and foot rest are then drawn up into the position shown in dotted lines in Fig. 1, and the seat slipped below the legs or the body of the patient, the seat being swivelled to adapt itself best to convenient handling of the patient. The patient is then slowly ushed on the seat from the bed over the f rame structure 10, when he can be placed in a sitting position, his back supported by pillows over back rest 40. The members 16 are swun upwardly and extensions 18 downwardl so as to form ahigh back for the chair furnishing additional support for the patient.

In the modification shown in Fig. 5, the end of the back 43 of the standard type of invalid chair is laid upon the edge or the bed. A separate structure consisting of a pair of tracks 16, 17 and 18, all hingedly connected, are laid over the seat of'the chair,

and the auxiliary seat pushed over the bed, as indicated in dotted lines in Fig. 5, and the patient transferred in the same manner, as explained above.

It is obvious that with the device de scribed herein, the actual handling of the patient is reduced to a minimum, the painful lifting of his body is entirely eliminated, and the patient transferred from his bed to the chair or vice versa, in a manner least disturbing to him.

While I have described my invention and illustrated it in two designs, I do not wish to limit myself to the particular forms shown. It will be understood that various changes in details of construction and ar rangement of parts may be made, and that some of the features of improvement are capable of use independently of others and in structures of other forms than those shown and described without departing from the principles or sacrificing any of the advantages of t e invention as defined in the appended claims.

What I claim as new, is: e

1. In combination with an invalid chair,

2. In comblnation with an invalid chair,

a pair of track members adapted to extend from the said chair to a bed, adjustable sup ports for the said track members engaging the said bed, and'an auxiliary seat slidably engaging the said track members.

3. In combination with an invalid chair, a pair of track members'adapted to extend from the said chair to a bed, adjustable supports for the said track members engaging the said bed, a platform slidably engaging the said track members, and an auxiliary seat rotatably mounted upon the said platform.

4. A transfer device for invalids consisting of a wheeled seat structure, a pair of track members hin ed thereto, forming a back support and being adapted to be placed in a substantially horizontal position to rest upon a bed, adjustable supports for the said track members engaging the said bed, a platform slidably enga ing the. said track members, and an auxi iary seatrotatably fastened to the said platform and adapted to travel therewith.

In testimony whereof I have hereunto set my hand.
